One sequence (B42), 72 residues long, was shown to function as an activator when transferred to the lexA DNA binding domain.
The recruitment model for transcriptional activation stipulates that eukaryotic transcription is driven mainly by recruitment of preformed RNA polymerase holoenzyme to specific sites on the DNA [ 3 ] . According to this model, peptides may bind one of numerous proteins that guide holoenzyme to the lexA binding site.
One of the peptide activators from the lexA-GFP/peptide library, derived from a frameshift in the insert, was tested for its ability to activate transcription when separated from the GFP structure and directly fused to the lexA binding domain.
A second library in which 15 residue-long random peptides were fused to the C-terminus of the lexA binding domain was also constructed.
In this study we used the DNA-binding domain of a lexA yeast two-hybrid construct to recover short peptides from random peptide libraries which function as transcriptional activators.
